text: 'In animals, parasitic infections impose significant fitness costs.1,2,3,4,5,6
Infected animals can alter their feeding behavior to resist infection,7,8,9,10,11,12
but parasites can manipulate animal foraging behavior to their own benefits.13,14,15,16
How nutrition influences host-parasite interactions is not well understood, as
studies have mainly focused on the host and less on the parasite.9,12,17,18,19,20,21,22,23
We used the nutritional geometry framework24 to investigate the role of amino
acids (AA) and carbohydrates (C) in a host-parasite system: the Argentine ant,
Linepithema humile, and the entomopathogenic fungus, Metarhizium brunneum. First,
using 18 diets varying in AA:C composition, we established that the fungus performed
best on the high-amino-acid diet 1:4. Second, we found that the fungus reached
this optimal diet when given various diet pairings, revealing its ability to cope
with nutritional challenges. Third, we showed that the optimal fungal diet reduced
the lifespan of healthy ants when compared with a high-carbohydrate diet but had
no effect on infected ants. Fourth, we revealed that infected ant colonies, given
a choice between the optimal fungal diet and a high-carbohydrate diet, chose the
optimal fungal diet, whereas healthy colonies avoided it. Lastly, by disentangling
fungal infection from host immune response, we demonstrated that infected ants
foraged on the optimal fungal diet in response to immune activation and not as
a result of parasite manipulation. Therefore, we revealed that infected ant colonies
chose a diet that is costly for survival in the long term but beneficial in the
short term—a form of collective self-medication.'

text: Entire chromosomes are typically only transmitted vertically from one generation
to the next. The horizontal transfer of such chromosomes has long been considered
improbable, yet gained recent support in several pathogenic fungi where it may
affect the fitness or host specificity. To date, it is unknown how these transfers
occur, how common they are and whether they can occur between different species.
In this study, we show multiple independent instances of horizontal transfers
of the same accessory chromosome between two distinct strains of the asexual entomopathogenic
fungusMetarhizium robertsiiduring experimental co-infection
of its insect host, the Argentine ant. Notably, only the one chromosome – but
no other – was transferred from the donor to the recipient strain. The recipient
strain, now harboring the accessory chromosome, exhibited a competitive advantage
under certain host conditions. By phylogenetic analysis we further demonstrate
that the same accessory chromosome was horizontally transferred in a natural environment
betweenM. robertsiiand another congeneric insect pathogen,M.
guizhouense. Hence horizontal chromosome transfer is not limited
to the observed frequent events within species during experimental infections
but also occurs naturally across species. The transferred accessory chromosome
contains genes that might be involved in its preferential horizontal transfer,
encoding putative histones and histone-modifying enzymes, but also putative virulence
factors that may support its establishment. Our study reveals that both intra-
and interspecies horizontal transfer of entire chromosomes is more frequent than
previously assumed, likely representing a not uncommon mechanism for gene exchange.Significance
StatementThe enormous success of bacterial pathogens has
been attributed to their ability to exchange genetic material between one another.
Similarly, in eukaryotes, horizontal transfer of genetic material allowed the
spread of virulence factors across species. The horizontal transfer of whole chromosomes
could be an important pathway for such exchange of genetic material, but little
is known about the origin of transferable chromosomes and how frequently they
are exchanged. Here, we show that the transfer of accessory chromosomes - chromosomes
that are non-essential but may provide fitness benefits - is common during fungal
co-infections and is even possible between distant pathogenic species, highlighting
the importance of horizontal gene transfer via chromosome transfer also for the
evolution and function of eukaryotic pathogens.

text: 'Hosts can carry many viruses in their bodies, but not all of them cause disease.
We studied ants as a social host to determine both their overall viral repertoire
and the subset of actively infecting viruses across natural populations of three
subfamilies: the Argentine ant (Linepithema humile, Dolichoderinae), the invasive
garden ant (Lasius neglectus, Formicinae) and the red ant (Myrmica rubra, Myrmicinae).
We used a dual sequencing strategy to reconstruct complete virus genomes by RNA-seq
and to simultaneously determine the small interfering RNAs (siRNAs) by small RNA
sequencing (sRNA-seq), which constitute the host antiviral RNAi immune response.
This approach led to the discovery of 41 novel viruses in ants and revealed a
host ant-specific RNAi response (21 vs. 22 nt siRNAs) in the different ant species.
The efficiency of the RNAi response (sRNA/RNA read count ratio) depended on the
virus and the respective ant species, but not its population. Overall, we found
the highest virus abundance and diversity per population in Li. humile, followed
by La. neglectus and M. rubra. Argentine ants also shared a high proportion of
viruses between populations, whilst overlap was nearly absent in M. rubra. Only
one of the 59 viruses was found to infect two of the ant species as hosts, revealing
high host-specificity in active infections. In contrast, six viruses actively
infected one ant species, but were found as contaminants only in the others. Disentangling
spillover of disease-causing infection from non-infecting contamination across
species is providing relevant information for disease ecology and ecosystem management.'

text: Cooperative disease defense emerges as group-level collective behavior, yet
how group members make the underlying individual decisions is poorly understood.
Using garden ants and fungal pathogens as an experimental model, we derive the
rules governing individual ant grooming choices and show how they produce colony-level
hygiene. Time-resolved behavioral analysis, pathogen quantification, and probabilistic
modeling reveal that ants increase grooming and preferentially target highly-infectious
individuals when perceiving high pathogen load, but transiently suppress grooming
after having been groomed by nestmates. Ants thus react to both, the infectivity
of others and the social feedback they receive on their own contagiousness. While
inferred solely from momentary ant decisions, these behavioral rules quantitatively
predict hour-long experimental dynamics, and synergistically combine into efficient
colony-wide pathogen removal. Our analyses show that noisy individual decisions
based on only local, incomplete, yet dynamically-updated information on pathogen
threat and social feedback can lead to potent collective disease defense.

text: Treating sick group members is a hallmark of collective disease defence in
vertebrates and invertebrates alike. Despite substantial effects on pathogen fitness
and epidemiology, it is still largely unknown how pathogens react to the selection
pressure imposed by care intervention. Using social insects and pathogenic fungi,
we here performed a serial passage experiment in the presence or absence of colony
members, which provide social immunity by grooming off infectious spores from
exposed individuals. We found specific effects on pathogen diversity, virulence
and transmission. Under selection of social immunity, pathogens invested into
higher spore production, but spores were less virulent. Notably, they also elicited
a lower grooming response in colony members, compared with spores from the individual
host selection lines. Chemical spore analysis suggested that the spores from social
selection lines escaped the caregivers’ detection by containing lower levels of
ergosterol, a key fungal membrane component. Experimental application of chemically
pure ergosterol indeed induced sanitary grooming, supporting its role as a microbe-associated
cue triggering host social immunity against fungal pathogens. By reducing this
detection cue, pathogens were able to evade the otherwise very effective collective
disease defences of their social hosts.

text: 'Two notes separated by a doubling in frequency sound similar to humans. This
“octave equivalence” is critical to perception and production of music and speech
and occurs early in human development. Because it also occurs cross-culturally,
a biological basis of octave equivalence has been hypothesized. Members of our
team previousy suggested four human traits are at the root of this phenomenon:
(1) vocal learning, (2) clear octave information in vocal harmonics, (3) differing
vocal ranges, and (4) vocalizing together. Using cross-species studies, we can
test how relevant these respective traits are, while controlling for enculturation
effects and addressing questions of phylogeny. Common marmosets possess forms
of three of the four traits, lacking differing vocal ranges. We tested 11 common
marmosets by adapting an established head-turning paradigm, creating a parallel
test to an important infant study. Unlike human infants, marmosets responded similarly
to tones shifted by an octave or other intervals. Because previous studies with
the same head-turning paradigm produced differential results to discernable acoustic
stimuli in common marmosets, our results suggest that marmosets do not perceive
octave equivalence. Our work suggests differing vocal ranges between adults and
children and men and women and the way they are used in singing together may be
critical to the development of octave equivalence.'

text: "Animals exhibit a variety of behavioural defences against socially transmitted
parasites. These defences evolved to increase host fitness by avoiding, resisting
or tolerating infection.\r\nBecause they can occur in both infected individuals
and their uninfected social partners, these defences often have important consequences
for the social group.\r\nHere, we discuss the evolution and ecology of anti-parasite
behavioural defences across a taxonomically wide social spectrum, considering
colonial groups, stable groups, transitional groups and solitary animals.\r\nWe
discuss avoidance, resistance and tolerance behaviours across these social group
structures, identifying how social complexity, group composition and interdependent
social relationships may contribute to the expression and evolution of behavioural
strategies.\r\nFinally, we outline avenues for further investigation such as approaches
to quantify group-level responses, and the connection of the physiological and
behavioural response to parasites in different social contexts."

text: "Background: Fighting disease while fighting rivals exposes males to constraints
and tradeoffs during male-male competition. We here tested how both the stage
and intensity of infection with the fungal pathogen Metarhizium robertsii interfered
with fighting success in Cardiocondyla obscurior ant males. Males of this species
have evolved long lifespans during which they can gain many matings with the young
queens of the colony, if successful in male-male competition. Since male fights
occur inside the colony, the outcome of male-male competition can further be biased
by interference of the colony’s worker force.\r\nResults: We found that severe,
but not yet mild, infection strongly impaired male fighting success. In late-stage
infection, this could be attributed to worker aggression directed towards the
infected rather than the healthy male and an already very high male morbidity
even in the absence of fighting. Shortly after pathogen exposure, however, male
mortality was particularly increased during combat. Since these males mounted
a strong immune response, their reduced fighting success suggests a trade-off
between immune investment and competitive ability already early in the infection.
Even if the males themselves showed no difference in the number of attacks they
raised against their healthy rivals across infection stages and levels, severely
infected males were thus losing in male-male competition from an early stage of
infection on.\r\nConclusions: Males of the ant C. obscurior have evolved high
immune investment, triggering an effective immune response very fast after fungal
exposure. This allows them to cope with mild pathogen exposures without cost to
their success in male-male competition, and hence to gain multiple mating opportunities
with the emerging virgin queens of the colony. Under severe infection, however,
they are weak fighters and rarely survive a combat already at early infection
when raising an immune response, as well as at progressed infection, when they
are morbid and preferentially targeted by worker aggression. Workers thereby remove
males that pose a future disease threat by biasing male-male competition. Our
study thus revealed a novel social immunity mechanism how social insect workers
protect the colony against disease risk."
